Overview

The Reflex RPRV20-F 20mm ¾ " inline pressure reduction valve is Australia Watermark approved and features a pressure adjustment range of 150-600kPa with a factory setting at 500kPa. The RPRV20-F pressure reduction valve features the same threads, fitments and similar physical sizes with many other valve manufacturers such as Reliance, AVG, Tomson, AW, Nefa and APO. This makes the RPRV20-F pressure reduction valve a perfect direct replacement to an existing valve with no plumbing pipe modifications required. 

The pressure reduction valves are commonly used in hot water services such as electric, heat pump, gas storage and solar hot water heaters across all mainstream brands in Australia such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart. The pressure reduction valve employs a membrane design inside with a stiff pre-loaded adjustable spring, opposed to a sliding piston mechanism found in a pressure limiting valve which often causes failures from clogging up. This design feature makes a pressure reduction valve more reliable than a pressure limiting valve, while functioning the same way in this application.

In real world installations, it is sometimes found that pressure limiting valves cannot limit pressures sufficiently in places where unusually high street mains pressures are present. This can cause troubles with ECV and PTR valves leaking on hot water services. The pressure reduction valves can be used in such situations and offer a far better pressure control from our infield experiences over the years in our own plumbing jobs in Brisbane. 

The pressure reduction valves can also be installed after water meters or just before entering houses. The pressure reduction valves can ensure a stable water supply pressure, despite the pressure fluctuations in the mains from the streets. 

The pressure reduction valve comes with a BSP 6mm test plug inbuilt, where an optional pressure gauge can be inserted for pressure measurement at the outlet. The optional pressure gauge is shown in the photo gallery and can be bought for extra. It must be noted that the pressure gauge is only intended to be used as a measurement tool and must be removed after use, as it could rust inside out if left in a wet environment for prolonged periods of time.

Nice for cable management
Real metal so it is very sturdy and if you tighten your screw it will be very stable too. I out it next to my monitor mount which provide a nice setup for cable management. It fits perfectly to a VESA 100x100 mount. I have a similar setup in my office but under the desk which makes it versatile.

Fits HP G2 dock
I have this mounting an HP-G2 Dock on the back of my Samsung 28inch 4K monitor. I used an additional flat plate to mount this to the left with the monitor arm going the plate and into the monitor. So good I bought a second one for my co worker so our desk don't have wires on them now.

HP G5 Dock Mount
Works as advertised! I purchased this as a test piece for our office supplied computers. It frees up space in the desk nd hides unsightly cords from view. I have it wall mounted behind the monitors and am very pleased thus far!
